I think that I'm about to take the plunge and buy a ATCS. The problem is, I don't know which one to go with. I looked at the Ique 110, the DigiQ, and the Stoker. All seem like really good units. Has anyone tried different models that can give me a good, objective comparison? Also, I'm not sure what fan size I need. I have a WSM 18", but might upgrade to a 22" at some point. Any advice would be greatly appreciated. Thanks!
